Introduce different sizes of dots in redirected sxcp progress output

There are 3 sizes now: short (default,1KB), long (8KB), scaled (equal to blocksize).

size was equal to number of bytes for each line with dots. Additional
line with summary was printed.

Giving --dot-size to sxcp user wants to use dots output, so enable it without checking if stdout is a tty.
